摘要
岩石地区地铁矿山法区间隧道衬砌的设计模式长期处于无章可循的状态,亟须合理化、规范化。从结构可靠度的角度出发,分3种模式(铁规破损阶段法、铁规概率极限状态法、建规概率极限状态法)对铁路系统和建工系统的设计模式进行分析研究,提出合理的可靠度设计方法进行P-Δ分析,并提出区间隧道设计中各个关键参数的合理取值。
The design patterns of metro mining method excavated rock tunnel linings are in a state with no criteria to follow and need to be rationalized and normalized. From the viewpoint of structural reliability, the essay analyzes the design patterns of railway system and building construction system from three modes （damage-stage method by railway speci- fications, probability limit state method by railway speci- fications, probability limit state method by building codes）. Then it advances the reliability design method by adopting p - A analysis, and puts forward reasonable values for the key parameters of tunnel design.
